ALMOND: FUNGICIDE EFFICACY
Group numbers are assigned by the Fungicide Resistance Action Committee (FRAC) according to different modes of actions (for more information,
see
/). Fungicides with a different group number are suitable to alternate in a resistance management program. In California, make
no more than one application of fungicides with mode of action Group numbers 1, 4, 9, 11, or 17 before rotating to a fungicide with a different mode
of action Group number; for fungicides with other Group numbers, make no more than two consecutive applications before rotating to fungicide with
a different mode of action Group number.
